Question 1
A magnetic field is decreasing rapidly in a copper coil. Describe the direction of the induced current and justify your answer using Lenz's Law.
💡 Hint: Consider how Lenz's Law articulates the relationship between flux change and current direction.
Question 2
In an electric motor, the coil rotates in a magnetic field. If the rotation speed is suddenly doubled, analyze the effect of Lenz's Law on the induced current.
💡 Hint: Think about what happens when there is a rapid change in motion and how the current reacts.
